American Car Craft Dodge Viper Side Hood Vent Grilles Billet Style with Viper Head 2Pc Polished 1992-2002 - Manual (Page 7)

Note: Care must be taken when cleaning your vent grilles. It is a good
idea to lightly dust your grilles with a clean soft cloth first in order
to prevent any particles from scratching them. Then wipe (using a new
clean soft cloth) with a good quality streak free glass cleaner.
NOTE: Once these grilles are installed you will want to open you hood
with extra care. Keep the hood perfectly centered while opening it so
the the grilles do not bump the side of the cars fender. Although not
required It works easiest when opened by two people.

NOTE: There is a plastic tab that might be in the way for mounting the grille on some older Vipers. If you have
this tab see Photo A, then you will need to cut off the corner.
